WebOnce there is motion, friction is less and the coefficient of kinetic friction might be 0.30, so that a force of only 290 N f k = μ k N = ( 0.30) ( 980 N) = 290 N would keep it moving at a constant speed. If the floor were lubricated, both coefficients would be much smaller than they would be without lubrication. WebStatic friction is the force of friction on an object that is not moving. If you push on a stationary block and it doesn't move, it is being held by static friction which is equal and opposite to your push. Once your push exceeds the maximum possible static friction (budging force = μN), then the block will start moving.
